I’ve seen this problem reported by many users of Sony Digital cameras. Many Sony Digicams switch off, when you try to turn it on - the camera simply displays cybershot, then the access light blinks for a moment & then the camera turns off.
This problem of switching off automatically, or turning off is noticed not only in cybershot DSC-S500 model, but also in models like Sony Cybershot DSC-W55, DSC-W170 et.al.
Most people try replacing their batteries with new ones, but still find the problem persist. Infact, someone had mentioned that this problem is a manufacturing / design defect of Sony in one of the forums. No definitely not! People hearing such stuff, have stopped trying to fix their camera!
Now, the solution to the problem is rather simple. Most probably you’re using a lead battery instead of alkaline battery. Though both lead & alkaline batteries may be of the same voltage rating (1.5v), the difference lies in the ampere rating. Sony Digicams need the power of alkaline batterie. So, just go on - replace your NEW batteries with alkaline batteries!
